With approximately 10 years of experience in B2B sales, new customer acquisition, and team management, I have consistently driven strong results across diverse industries. My strengths lie in solution-based sales execution and deep domain knowledge in both financial and advertising sectors. At American Express, I led initiatives that addressed critical client issues—such as resolving Google Ads payment disruptions and facilitating card adoption in unpenetrated industries. I also contributed to strategic planning and organizational management, delivering both quantitative and qualitative outcomes.
